AP BIOLOGY

Detailed explanation-1: -A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.

Detailed explanation-2: -A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring.

Detailed explanation-3: -A species is often defined as a group of individuals that actually or potentially interbreed in nature. In this sense, a species is the biggest gene pool possible under natural conditions.

Detailed explanation-4: -Species is defined as a group of organisms capable of interbreeding and creating fertile offspring. This means two organisms are the same species if they can have offspring and those offspring can also breed and produce offspring.

Detailed explanation-5: -The Biological Species Concept defines a species taxon as a group of organisms that can successfully interbreed and produce fertile offspring. According to that concept, a species’ integrity is maintained by interbreeding within a species as well as by reproductive barriers between organisms in different species.
